class WatcherError(Exception): (source)
Known subclasses: invoke.exceptions.ResponseNotAccepted
Generic parent exception class for `.StreamWatcher`-related errors. Typically, one of these exceptions indicates a `.StreamWatcher` noticed something anomalous in an output stream, such as an authentication response failure. `.Runner` catches these and attaches them to `.Failure` exceptions so they can be referenced by intermediate code and/or act as extra info for end users. .. versionadded:: 1.0
